To all whom t may concern.- l

Be it known that I, VICTOR DURAFORT, a citizen of France, residing atParis, France, have invented certain new `and useful Improvements inApparatus for Containing Compressed Carbonic Acid and Charging Water orother Liquids Therewith, of which the following is a speciiication. Myinvention has for its object to provide siphons and cartridgescontaining compressed carbonic acid wherebyaerated water or other liquidmay be produced charged with any desired proportion of gas, thearrangement being such that any proportion of the carbonic acid or thewhole of it can be admitted to the water or other liquid to beimpregnated therewith.

I will describe my invention with reference to the accompanyingdrawings.

Figure 1 represents in section an apparatus according to my invention.Fig. 2 is a section of the upper part of the head at right angles toFig. 1. Fig. 3 is a transverse secg tion taken along the line 1 1 ofFig. 2. Fig. 4 is an enlarged section of the upper part of thecarbonic-acid cartridge or container.

2 represents the said cartridge or container, which is inclosed in achamber 5 at the top of the Siphon-head. The part 4. of this chamber maybe of cast-iron or other suitable material, with the usual or anysuitable cocks and valves for drawing o the aerated liquid, and when thecartridge is in place the top part 3 is screwed onto the lower part 4 byears 7.

A ring 8 of india-rubber or any other elastic material is placed betweenthe parts 3 and 4' in order to insure an air-tight joint. The top part 3includes a chamber 9, separated from the chamber 5 by an elasticdiaphragm 10, normally kept in a horizontal position by a screw-cap 11,which exerts its pressure on a ring 12, which in turn bears on the edgeof the diaphragm.

y ln a sleeve 13, screwed into the top of the cap 11, slides a piece 14,which can be forced in by pressure on the upper button 15, whereby thepiece 14v is caused to descend and to carry with it the button 16, whichpresses on .the diaphragm 10, which in turn depresses the button 17,which is on a stem passing through the opening in the valve-casing atwhen no pressure is exerted on the button 15. v

Carbonic acid can thus be allowed to escape from the cartridge 2 verygradually into the water or liquid.

When it is wished to discharge the whole of the carbonic acid from the`cartridge into water or liquid, the valve 1S can be lowered so that thecartridge can be completely emptied without the necessity for theoperator to keep the pressure on the button 15. In this case instead ofthe button 15 being pressed it must be turned, for which purpose (seemore particularly Fig. 3) the piece 14 is provided with a cross-piecewhich engages in a crossslot in the part 13, so that when rotated itcarries with it the said part 13, which. therefore screws down into thehead 11, and the button 16 presses on the diaphragm 10, which inturnpresses on the button 17 to open the valve 18, which can thus beallowed to remain open until the carbonic acid has escaped from thecartridge 2, when the button 15 can be screwed back and the parts resumetheir normal position.

To prevent danger from too sudden a discharge of the contents of thecartridge 2, I provide a chamber 22 with a small hole 23, such chambercontaining a safety-valve 24, normally pressed to its seat by a spring25. This valve controls a channel 26, communieating with the interior ofthe siphon.

When the internal pressure exceeds the limit to which the spring is set,the valve 24 is pressed from its seat and the excess of gas escapesthrough the hole 23 until the normal pressure is restablished, when thespring 25v closes the valve 24:. l do not limit myseltl to the precisedetails illustrated.

Having now particularly described and as- IOO certained the nature of mysaid invention and in what manner the same is to be performed, I declarethat what I claim is l. An apparatus for charging liquids with gas,consisting of acartridge or gas-container an outlet-valve for the gasclosed by interior pressure, a stem entering said container, its outerend lying in a chamber containing the cartridge and a movable slideentering a screw-cap for said chamber and supported `directly over saidstem by an elastic diaphragm which separates the interior of thescrew-cap from said chamber, substantially as described.

2. An apparatus for charging liquids with carbonic-acid gas consistingof a cartridge or compressed-gas container inelosedin a chamber, anoutlet-valve for said container closed by interior pressure of said gas,a stem entering the cartridge and having one end on said valve, theother end being on the outside, a threaded sleeve tapped into ascrewcap, which closes the cartridge-containing chamber a slide arrangedto move in said sleeve an elastic diaphragm between the slide andthestem of the outlet-valve, and a cross-head on VICTOR DURAFORT.
